“OpenAI and Anthropic will quickly join the "power players" in digital advertising by further diving into native ad formats. ... They will attract more ad dollars and could easily become part of the top echelon of ad platforms in just a year or two.”

Follow-up

Tracking well so far. OpenAI was piloting ads in ChatGPT in the US by March 2026 and expanded the pilot to the UK, Mexico, Brazil, Japan and South Korea by August 2026 (OpenAI). Anthropic has yet to introduce ads. The full call - both joining the "power players" within a year or two - stays open through 2027.
